Study to Evaluate the Efficacy and Safety of ABT-450/Ritonavir/ABT- 267 (ABT-450/r/ABT-267) in Japanese Adults With Genotype 2 Chronic Hepatitis C Virus (HCV) Infection

An Open-label Study to Evaluate the Efficacy and Safety of ABT-450/Ritonavir/ABT-267 (ABT-450/r/ABT-267) Co-administered With Ribavirin (RBV) for 12 or 16 Weeks in Treatment-Naïve and Treatment-Experienced Japanese Adults With Genotype 2 Chronic Hepatitis C Virus (HCV) Infection With and Without Compensated Cirrhosis (GIFT-II)

This is a Phase 3, randomized, open-label, multicenter study, enrolling non-cirrhotic and cirrhotic subjects. The purpose of this study is to evaluate the efficacy and safety of ABT-450/r/ABT-267 co-administered with weight-based RBV for 12 or 16 weeks in adult chronic HCV genotype 2-infected treatment-naïve and interferon (IFN) treatment-experienced subjects with and without compensated cirrhosis.

Inclusion Criteria:

• Chronic HCV-infection prior to study enrollment
• Screening laboratory result indicating HCV genotype 2 infection

• Voluntarily sign an informed consent

Exclusion Criteria:

• Co-infection of Hepatitis B Virus (HBV), human immunodeficiency virus (HIV) and any HCV genotype other than genotype 2
• Prior therapy with direct acting antiviral agents for the treatment of HCV, including telaprevir, simeprevir and boceprevir
• Any cause of liver disease other than chronic HCV-infection, including but not limited to the following: hemochromatosis; alpha-1 antitrypsin deficiency; Wilson's disease; autoimmune hepatitis; alcoholic liver disease; drug-related liver disease
• Clinically significant laboratory abnormalities
• Uncontrolled clinically significant disease, disorder or medical illness
